Biodiesel is too easy to make to have to wait to get it from a supplier. that said, it is a bit messy and time consuming, so if you already have an overly busy schedule, the next best thing might be a small bottle of canola oil(fresh) or 1-2 gallons of commerical biodiesel. I have been burning mostly B100 for the last 11/2 years adn I plan on getting my injectors tested before I put the turbo on. I will let you all know how they test out. Keep in mind, homebrew, and probably not ASTM spec either..., but as far as I can tell fromperformance, no ill effects.
